Water quality safety detection device and water quality detection method

Abstract

The invention discloses a water quality safety detection device. The water quality safety detection device is provided with a paper-based chip, a light source and an image acquisition device; a plurality of detection regions are uniformly arranged on the paper-based chip along the peripheral direction on the same radius; a sample feeding region is arranged at the center of the paper-based chip; the light source is arranged at the upper end of a sector-shaped region; the image acquisition device comprises a camera arranged at the upper end of the sector-shaped region and a processing system; the processing system is connected with a storage device; the processing system is used for acquiring color developing information, which is tested by hydrophilic test paper, of the sector-shaped regionthrough the camera, comparing the color developing information with a storage module and outputting a comparing result; different test paper is set in a plurality of detection regions of the paper-based chip on the same radius, and images of test samples are acquired one by one by utilizing a camera device; the images are compared with standard structures of samples stored in the processing system, so that the content of various elements in a water sample can be rapidly detected; the device is simple in structure and convenient to use; the time of measuring the various elements in the water sample is greatly reduced and the measurement speed of the water sample is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental detection devices, and in particular relates to a water quality safety detection device and a water quality detection method. Background technique [0002] If there is no water, a person can generally only survive for 10 days at a temperature of 16-23 degrees Celsius, and only 3 days at a high temperature of 36 degrees Celsius. When working and living in the field (such as troops training in the field, fighting in the field, exploring in the field, traveling, investigating and surveying, etc.), they often cannot directly obtain clean drinking water and cannot determine the drinking safety of the water quality, which brings a lot of inconvenience and trouble. Existing sewage monitoring requires large-scale and expensive laboratory equipment and professional technical personnel, and the current technical support cannot be completed by the township level government. In addition, the current mi...

Problems solved by technology

New technologies for detecting water pollution have been developed, but for multi-target objects, electrochemical technology needs to replace the selective electrode, which is complicated to operate; test paper mostly uses the traditional soaking method, and it is difficult to achieve diversification of detection targets
